S = true
~s = false
-------------
j = false
~j = true
-------------
~s = false and j = false, so,
~s v j = (false) v (false)
~s v j = false
-------------
Similarly,
s v ~j = (true) v (true)
s v ~j = true
-------------
We have
~s v j = false
and
s v ~j = true
which lead to this when we conjunct the two logical expressions
(~s v j) ^ (s v ~j) = (false) ^ (true)
(~s v j) ^ (s v ~j) = false

The final answer is false
1st quadrant is the answer
Answer:
easy it 53847263
Step-by-step explanation:
it is
0.3km=300m
300m:500m
(/100)
3:5
3+5=8
0.3km= 3/8
500m= 5/8
X = y - 3 (equation 1)
2x + y = 12 (equation 2)
Substitute equation 1 into equation 2, replacing every x value with equation 1
2(y - 3) + y = 12
Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)
Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3
Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12
Therefore, x = 3 and y = 6
